Subject: [PATCH] staging: p80211conv: Rename local foo to decrypt_check

This change renames the local variable foo to decrypt_check in functions
skb_ether_to_p80211(...) and skb_p80211_to_ether(...), giving intuitive
meaning to the identifier.

It also indents the parameters to match the the opening parentheses.
